Funders, academic institutions, journals and data service providers adopt open access policies including the publication of data underlying research results. While these mandates are an important step towards open science, they often neglect that there is no ‘one-size-fits-all’ approach to open research data across academic disciplines. Different disciplines produce different types of data and have various procedures for analysing, archiving and publishing it. Some have established data management procedures, norms or policies, making their research data open by default, while others do not. Consequently the Research Information Network (RIN) states in a report that

‘if the policies and strategies of research funders, universities and service providers are to be effective in optimising the use and exchange of scholarly information, they must be sensitive to the practices and cultures of different research communities.’

This briefing paper presents the current state of open research data across academic disciplines. It describes disciplinary characteristics inhibiting a larger take-up of open research data mandates. These characteristics include data management practices, disciplinary norms of data sharing, career-related factors, infrastructural factors, and legal and ethical questions of public access, Additionally, the paper presents the current strategies and policies established by funders, institutions, journals and data service providers alongside general data policies.
